This replica nautilus 711812 blue houses the 7118/1200A-001 reference in a 35.2mm stainless steel case with the blue dial that has become the defining color of the entire Nautilus lineage. Blue on steel is where the Nautilus story began with the original 3700/1A in 1976, and Patek Philippe has maintained that combination across every generation since. The horizontal embossing on a blue surface produces a gradient effect as light moves across the grooves, shifting from deep navy to bright cobalt depending on angle and environment.

The blue dial catches light differently across each embossed ridge, creating a visual depth that photographs rarely capture accurately. In person, the surface appears to shift continuously as the wrist moves.

Caliber Performance

The automatic 324 SC caliber provides the same timekeeping architecture used across both the mens and ladies Nautilus families. Its compact dimensions allow the 35.2mm case to stay thin enough to slide under a cuff without catching. Blue has become so central to Nautilus identity that collectors often refer to a “Nautilus blue” as its own color category, distinct from the blues used by competing brands. Explore the 5719/10G-010 in white gold for a diamond-set mens Nautilus that takes the design in a completely different direction. The complete Nautilus collection spans from minimalist steel configurations to fully jeweled precious metal references.

How It Compares

Among the 7118 ladies references, the blue dial on steel is the version with the strongest visual connection to the mens 5711/1A blue that launched the modern Nautilus phenomenon. It reads as sporty and confident without relying on precious metals or diamond accents. The 35.2mm case wears larger than the number suggests because the integrated lugs extend the visual footprint on the wrist. This replica nautilus 711812 blue carries the original Nautilus color philosophy into a 35.2mm automatic format built around the 324 SC caliber.
